Casey Aldridge Recovering, Moved Out of ICU

Doctors at the University of Mississippi Medical Center in Jackson, Miss., planned to move Casey Aldridge out of the intensive care unit as early as last night.

"They said it was borderline whether [Casey] needed surgery or not," says a hospital source, "but they've taken some scans and see no further damage."

Aldridge, the father of Jamie Lynn Spears' 10-month-old daughter Maddie Briann, was hospitalized with a head injury that he suffered when he flipped his pickup truck on a two-lane road in Louisiana at 1:30 a.m. Sunday.

The accident - during which three of the five passengers, including Casey Aldridge himself, were ejected from the truck – occurred after a bachelor party for Aldridge's cousin at nearby Lake Bruin on Saturday, according to the source.

The two others thrown from the truck suffered less serious injuries.

"Jamie Lynn has been at the hospital, and all indications are that she is holding up well," a Spears family source reports. "[Jamie Lynn Spears] was in the ambulance with Casey, and Casey's sister followed in the car."

Given the nature of the incident - fatalities are common, even likely for a human ejected from a vehicle during an accident - the police are surprised that Aldridge and his four passengers are faring as well as they are.

"It's an anomaly that no one was injured more seriously," says a Louisiana State Police spokesman. "Usually, you would see serious injuries or fatalities."
